AI Technical Summary
Technical Problem
The issue with existing pipes is that when the dimensions of the outer pipe are smaller than standard dimensions, inserting the inner pipe requires a large force due to the strong pressing against recesses, making it difficult to connect them.
Method used
The pipe design includes an outer pipe with an outer protrusion that elastically deforms radially outward, allowing the inner pipe to be easily inserted by applying a smaller force, while also preventing fluid leakage through the gap between the pipes.
Benefits of technology
The design enables easy insertion of the inner pipe into the outer pipe with minimal force and effectively prevents fluid leakage, even when the outer pipe dimensions are smaller than standard, by utilizing elastic deformation of the outer protrusion.

Abstract
To provide a technology to easily insert an inner pipe to an outer pipe.SOLUTION: A pipe is a pipe in which a fluid flows. The pipe includes an outer pipe and an inner pipe inserted to the outer pipe from one end side of the outer pipe. The outer pipe includes: an outer cylindrical portion having a cylindrical shape; an outer contact portion recessed to a radial inner side of the outer cylindrical portion with respect to an inner face of the outer cylindrical portion, and constituted to be kept into contact with the inner pipe; and an outer projecting portion at least partially disposed on the outer contact portion and projecting to a radial outer side of the outer cylindrical portion with respect to the outer contact portion at its inner face opposed to the inner pipe. The outer pipe is elastically deformed to the radial outer side by elastic deformation of the outer projecting portion.SELECTED DRAWING: Figure 5
